Air temp sensor giving weird readings

Kash_ · July 05, 2008, 12:45:33 PM

Hi guys, not sure what might be causing this but hoping someone can shed some light?

My air temp sensor gives some weird readings on the Power FC Commander... sometimes it will be okay e.g. 30 when crusing then other times it will be 5 or -10., etc.. I\'ve seen it do a countdown from 10 to -2 lol... it seems to happen randomly... is this the start of a faulty air temp sensor?

My water temp sensor did the same thing, resulted in a broken engine.

sorry to hear that....

was the reason for the weird readings because the sensor had gone?

Not really sure but it was stripped down and put back together been ok ever since. I would imagine air temp sensor would cause the same problem if doing the same thing running to rich or to lean for the real airtemp.

Had this happen to me with the air temp sensor changed it and has been fine ever since.

what sort of temp sensor is it? Is it a thermocouple type? The wire could be pinched as it looks as though it is going to ground. Either that or it is Fubar\'d

Yeah, you gotta be careful if the ECU is seeing strange readings. It can base timing and fuelling on the air temp.

mine did this bro but would show -35 randomly and stay that way.

i changed it and its fine.

cool thanks for all the replies guys... looks like a new air temp sensor is in order... anyone know where I can get a new one from?

it\'s the standard FD air temp sensor
